First, hero Jill Valentine will be able to swim underwater, a first for the Resident Evil series. It'll be interesting to see whether the developers implement gyroscope controls for controlling the camera.

That said, gamers can also expect to use a flashlight to see, as well as underwater weapons to combat new enemies, one of which may be a giant squid like creature.

You might be able to upgrade Jill's air supply over time.

Next, Chris Redfield has teamed with a new character named Jessica, who appears to be a bit whiny.

There's also a mysterious and masked man, identity unknown.

Finally, and this is a big one, zombies will make a triumphant return to the franchise after disappearing from Resident Evil 4. Just don't expect the same undead freaks from the first three games.

While none of this info sheds light on the story per se, look for additional Resident Evil Revelations news next month.
